That is debatable. A healthy 2013 or 2014 has a better guard rotation than 2011. CJ Watson, Ronnie Brewer, Korver, and Bogans are basically trash. Rose was really
the only player who could set up the offense or create for others. Now they have Heinrich and Nate as backups, Butler as a starting Sg and Belineli as his backup. The front court is basically the same because Asik was not even used in 2011. So same frontcourt but with an improved back court. You can argue that more depth can improve the defense as well.
The Heat can still beat any type of Bulls team but it is not 100% guaranteed as they are not the same 2011 team. Then again the Bulls have Boozer and I think as long they have him they have no chance at beating the Heat
. It will be interesting to see these 2 squads go at each other at full strength next year.
